WHARE.

i Applicationy led November 6.1923. Serial No.1z673f,113.

This invention relatesitowharf or pier construction, and its chief object is toprovide .light and kinexpensive but effective means for retaining in place the bank or wharf.'r In many situations my invention can be used in lieu of costly sheet plling, with equally good results.

One form ofthe invention is illustrated in the accompanying drawingyin which Fig. 1 is a vertical cross section. y Fig. 2 a rear elevation before the filling on the shoreward end or side isfput in place. Fig. 3 is a detailview, in elevationof the upper end of one of the retaining sla is, showing the eyes for hanging the slabs from the wharf.

Fig. 4 is a detail plan view the row of slabs. t y y ln the drawing, 10 represents the ywharf structure generally, at the shore end or side thereof, the top of which vis carried by supporting members 11, 12. In the particularl situation illustrated the bottom 13 of the river7 slip, or other` water way, slopes up to a point relatively close' to the top of the wharf.

Back of the wharf is shown the back-till 14. The horizontal thrust of this till is taken byk a retaining wall or bulkhead composed' of one or more concrete slabs lo, suspended from the wharf, as by means of eyeolts or --loops 16 engaging studs' 17 projecting from the beam 18 of the wharf. The slabs extend down into the bottom 13 far enough to Give 1 secure anchorage against lateral dispacement by the thrust of the fill. some cases, as for example where the bottom is soft, it maybe necessary or desirable to run a bracing beam 19 between the slabs and the row of piles 12, or consolidate the soil by rock filling or riprap, orboth, as indicated.A

vof a portion of devices ribbed and grooved slabsladjoining. .Dis-y, placement of the `slabs/ individually 'is thus resisted. I l y The slabs'are. reinforced in any convenient and suitable -manneigand 'I have merely indicated the fact, diagrammatically, by showing reinforcing members at 22, Fig. 3.

It is to be understood that theinvention is not 'limited to the particular' construction herein ilustrated but canr beembodied in f other forms without ldeparture from vits'.

wayvto hold their lower ends against' lateral pressure vexerted by vback filling.

to its `shoreward face, aseriesl of concrete slabs arranged-slde by side along the shoreward face ofithe' wharf,v having all parts thereof suspended in tension from the wharf structure and extending downwardly into 2. Awharf having a row of piles adjacent the bottom of the water way to form aretaining wallor lbulkhead for a back fill, and means between the slabs and the saidpiles to transmit to the latter the horizontal thrust of the yback till.` r 1 f 3. A wharf having a row of piles adjacent to its shoreward face, a' plurality of concrete slabs pendantly suspended by their yupper ends from the main structure along its shoreward face only. and havingall portions in tension from said supporting to forma retaining wall or bulkhead or a back fill, and a beam extending horizontally between the said piles and t'hevlower poroint tions of the retaining slabs to transmit vto the piles the thrust of the back till.

4. A wharf havingva row of vertical suprloo porting piles adjacent to its shoreward face and .a row of batter pilesy to take horizontal pressures exerted on the upper portion of the Wharf, a row of concrete slabs hung side by side from the upper portion of the wharf and extending downwardly into the bottom of the water `way to form a retainingwall or bulkhead for a back fill, andV means enibedded in the bottom of the Water Way, between the slabs and the Vertical supporting piles toy transmit to the latter the horizontal thrust' exerted by the backfill on the lower portion of the retaining slabs.

5. A Wharfhaving along its'shoreward face ahrow of studs projectingsubstantially horizontally therefrom, yand a row of con-` crete slabs arranged side by side andV having in their upper ends loop'devices engaging the studs to suspend pendantly the slabs in tension-therefrom.

6. The structure described in claim 5, in

a retaining Wall or bulkheadv t0 take the thrust of filling yback of the.,Wharijcomprising a series of concrete slabs pendantly suspended by and at and'only from 'the' shore- Ward `Vertical face of 'the Wharf and hanging substantially Vertical from said sole'point of suspension, said slabs havingy their lower ends anchored against lateral displacement.-
